Patent CA-2403568-A1 (CA)
Inventor: VAN DE VEN ANTONY
IPC: G06F13/00
Filed: 2001-03-23
Abstract: This invention provides a method and apparatus to selectively compress digital image data for the supply of that information to digital display screens or storage. The invention utilizes a digital input containing a non-linear representation between the value and the intended intensity and linearizes this into a higher order number. If the higher order number is below at least a first threshold, it is transmitted or stored on a lower order data system noting that the higher order bits or channels should all be zero. If the higher order value is above the threshold, the highest order bits of that value are transmitted or stored on the lower order data system so that only the lowest order bits are lost. The received input from the lower order data system can then be decoded and the data sent to drive a digital display or otherwise utilized. As the linearization process introduces substantial errors in the lower order numbers and minimal errors in the higher order numbers, this invention seeks to increase the accuracy of those lower order numbers by offsetting this against introducing some additional error into the higher order numbers. Further embodiments utilize multiple stages of compression.

Title: Method of evaluating logs to predict warp propensity of lumber sawn from the logs
Inventor: FLOYD STANLEY L
IPC: B27B1/00
Filed: 2002-10-07
Abstract: A method of predicting warp of lumber that might be sawn from any given log is disclosed. The method involves measurement of stress wave velocity in the tree stem, either as a standing tree or felled log. A scan is then made to define the exterior geometric configuration of the log. In particular, measurements relating to lack of longitudinal axis linearity (sweep) or irregularity of cross sections of the log are important. Stress wave values and selected geometric parameters are entered into a multivariate regression equation to predict warp propensity of lumber that might be sawn from the log. Separate equations are required for each species for prediction of crook and bow. The equations are originally derived by examination of a representa-tive population of logs of the particular species and locale and measurement of warp in lumber sawn from the logs. The stress wave information may be combined with the geometric characteristics in the computer associated with a log scanner at the green end of a sawmill. Logs determined to produce warp prone lumber can be iso-lated and used to produce other products such as timbers or plywood where warp is not as critical.

Abstract: An irradiation device, which is particularly suited for carrying out photodynamic diagnosis or therapy in the field of medicine, comprises a number of flat luminous segments (1-4) that each generate a radiation that is directed toward a specified surface (A) to be irradiated. The individual luminous segments (1-4) are arranged at angles to one another so that the directed radiations of the luminous segments (1-4) overlap in an essentially complete manner on the surface (A) to be irradiated when the irradiation device is placed at a designated distance (D) from said surface (A) to be irradiated. This enables, also in the event that each individual luminous segment (1-4) has only a relatively low intensity of irradiation, a homogeneous irradiation of the surface (A) to be irradiated with a high intensity of irradiation. The luminous segments (1-4) preferably have a multitude of uniformly distributed luminous means (6), particularly light-emitting diodes or laser diodes, in order to enable a uniform irradiation of the surface (A) to be irradiated.

Abstract: The multi-layer fibrous product and a process for producing it. According to the present invention the fibre product comprises at least two overlapping fibre layers, whereby the one that forms the top layer of the product contains filler and is lighter than the layer under it and is at least essentially opaque. According tothe present invention the filler of the top layer consists at least partially of cellulose or lignocellulose fibrils, on which light scattering material particles have been precipitated. The present invention can be used, for example, to produce white surface liner with a lighter top layer without impairment of the strengthof the surface. Thus, the grammage of the layer can be at least about 5% by weight less than a top layer, which has the corresponding opacity and formation, and which has been produced from the same fibre material and mineral pigments.
